Description
Technical field
The invention belongs to be vented butterfly valve equipment technical field, and in particular to a kind of exhaust butterfly valve apparatus.
Background technique
With the increasing demand for brake systems for commercial vehicles, by cannot have been fully met to traditional braking system upgrading
The use demand of client, so another mode of braking-auxiliary braking that come into being, although master is not achieved in auxiliary braking
Braking system exports so big brake force, but vehicle is also not requires to be gone with so big power every time in the process of moving
The abrasion of friction plate had both been reduced when vehicle being stopped dead, such as needing to slow down using auxiliary, moreover it is possible to the effect of braking deceleration is played, so
Exhaust butterfly valve is born as a kind of completely new auxiliary product.
Automobile exhaust butterfly valve generally includes butterfly valve cylinder, ball bowl, valve body, butterfly valve valve block, rotating shaft assembly etc., butterfly valve valve block
It is located in valve body, in off working state, butterfly valve cylinder does not have stroke output, at this time fully open position at butterfly valve valve block, and engine is just
Normal exhaust；When driver needs that braking is exhausted, air inlet has gas input, and butterfly valve cylinder has stroke output at this time,
Ball bowl is released to the right under the action of butterfly valve cylinder, is driven shaft, is acted on butterfly valve valve block on valve body, the outer diameter of butterfly valve valve block
It is attached in the inner hole of valve body, row achievees the effect that exhaust brake, when releasing exhaust brake, butterfly valve valve block is in butterfly at seal chamber
It is resetted under the action of return spring in valve cylinder.Since vehicle use environment is different, result in certain working regions, vehicle
Environment very severe, such as dumper just has a large amount of dust in mine loading；Concrete mixer is carried in cement stirring station
When goods, a large amount of concrete grey etc. is just had, this specific workplace beat the working life for being vented butterfly valve can greatly
It is close to be used for work although can carry out various dustproof construction designs to exhaust butterfly valve cylinder to guarantee working life for discount
The valve body and butterfly valve valve block of envelope can not go dust-proof, and valve body and butterfly valve valve block take rigid seal, and the production during the work time
Product are installed at the exhaust pipe of engine, and instantaneous operative temperature can reach 650 degree, sealing element can not be taken dust-proof at all, so
It is easy in the exhaust butterfly valve of above-mentioned environmental work because occurring the impurity such as carbon distribution, dust accumulation between valve body and butterfly valve valve block.Existing skill
Center of the shaft of art rotating shaft assembly by butterfly valve valve block, the bilateral symmetry of butterfly valve valve block, when releasing exhaust brake, butterfly valve valve
It is resetted under the action of return spring of the piece in butterfly valve cylinder, when occurring the impurity such as carbon distribution, dust accumulation, meeting between valve body and butterfly valve valve block
There is valve body and hair fastener or even stuck when butterfly valve valve block relative motion, directly results in assembly failure.In addition traditional butterfly valve is all
Increase the power of return spring in butterfly valve cylinder to increase the power of reset, but spring force can have failure, plus at this work
Temperature is higher, spring can be made to become fragile, it is easier to the Stiffness of acceleration spring, so after a period of operation, due to not having
Enough returning place forces make butterfly valve valve block reset and lead to assembly failure.Traditional exhaust butterfly valve uses the economic profile of gray cast iron
Material, because the instantaneous operative temperature of exhaust butterfly valve can reach 650 degree, however gray cast iron works can generate at such high temperatures
Slight deformation, so that valve body and valve block are directly stuck in cooperation, if because of the hair fastener phenomenon that valve body and valve block deformation generate,
Even when there is again big reset force to be also difficult to make valve block normal crankmotion in valve body.
